Copper Mining And Processing Processing Copper Ores. After the copper ore is crushed, liquid is added to make it a slurry. the slurry is a mix of valuable copper ore minerals and “worthless” rock, called gangue (pronounced “gang”). the slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. chemical reagents called.

Copper extraction - Wikipedia

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
